I have to say, I saw red flags going up when I read your post, too (I'm a recovering addict).
It may just be his pride, but for a person who is working hard at her recovery, I don't think his blowing up is very recovery-like.
You don't deserve his temper tantrums, no matter what the cause. As for me, I would be watching the money situation very carefully and giving him only limited access.
Thanks to recovery, I've learned to stop taking out my frustrations on others. I caused all my own problems, and it's no one else's place to make things all better.
Hugs and prayers!
